FRAME FOR BUILDING OPENINGS Filed Jan.4, 1965 28 6 .9 ATTORNEY 3,213,980FRAME FOR BUILDING OPENINGS Sven Erie Persson, 1676 Commerce Drive,Stow, Ohio Filed Jan. 4, 1963, Ser. No. 249,477 4 Claims. (Cl. 189-75)The present invention relates to metal frames for windows, doors andother openings in buildings and more particularly is 'directed to suchframes constructed of extruded or formed metal sections connectedtogether with insulation therebetween.

Heretofore the metal framing used in building construction in whichclosure members such as doors or sashes are mounted has not providedadequate insulation between the outer frame portion and Ithe inner frameportion or between .the frame porti-ons .and sash or door portion. Insome building constructions only a one piece or unita-ry .frame memberis used while in other buildin-g constructions when an outer and innertrame portion were used, no rigid connection therebetween withinsulation interposed thereat was provided.

An object ot the present invention is therefore to provide metal tramesformed of rigidly connected outer and inner frame portions withinterposed insulation for use in construction purposes in which doors orsashes are to be mounted. l Another object ofthe present invention is toprovide rigid'lyconnected outer and inner frame port-ions withinsulation .at the point of connection therebetween 4as well asbetweenthe trarne porti-ons and the sash or door member.

A -further object of the present invention is to provide 'metal framescomposed of inner and outer portions Wherein one of the frame portionshas a U-shaped groove forming portion into which a flange of the othertrame porti-on is inserted with insulation therebetween, land theU-shaped portion is compressed to -grip the straight portion Iand theinterposed insulation to provide an effective insulated rigid connectionbetween the trame portions.

A still :further object of the present invention is to provide ra rigidinsulated connection between portions of a frame member wherein ribs areprovided on cooperating ange and .groove members.

An additional object of the present invention is to provide a novelmounting of a IJframe of a window or door to the wall of a building.

lFurther objects of the invention will become apparent when consideringthe following description taken in conjunction with the drawings inwhich:

FIGURE '1 is la perspective vie-w showing a window sash mounted in aframe disposed in a building; .and

FIG. 2 is a section taken along the lin-es I-I-II of FIG. 1.

In FIG. 1 there is shown a window structure i1 including a frame 2 and asash 3 carrying the lwindow pane 4 mounted in an -opening of wall 5. Ifdesired, the sash 3 can be made Iof an inner portion 3a and an outerportion 3b each provided with a window pane 4 as shown in FIG. 2 and inprior U.S. Patents (Nos. 2,694,841; 2,838,109; 2,845,1116 and 2,975,492.As can be seen the window panes 4 are mounted in sash portions 13a and3b by means of :gaskets -or sealing strips 7. The fra-me 2 consists ofan inner frame portion v8 and an outer `frame portion 9. rIIhe trameporti-ons l8 and 9 are generally made from metal and preferably fromextruded or for-med metal such .as aluminum or steel or an alloythereof. Inner trame portion l8 comprises a U-shaped channel portion\11, a U-shaped portion 1112 and a stra-ight ilangedike portion '16.

The U-shaped channel portion 11 has depressions 14 into which legs llSof an anchor 16 fit. 'Ilhe anchor 116 3,213,980 Patented Oct. 26, 1965lCC has yanother lleg 1.7 bolted into the interior section -18 of wall Sby lmeans of anchor bolt 19. There are a number 4of anchors 'i116 spacedaround the opening in interior wall '1 8 in order to effectively anchorthe inner trame portion 8 therein.

The U-shaped portion |112 has a leg 12' which abuts against the coveringmaterial over the interior Wall 18 :such as plaster, dry wall etc.,while leg 12 serves as an ab-utment .against which anchor 16 abuts forlending strength and rigidity thereto. Leg :12 is also la common leg:between yU-shaped portion 12 and U-shaped channel portion r11.

Straight llange portion 13 extends trom U-shaped channel portion 111 atsubstantially right angles to leg *11' thereof. Teeth or ribs 13 and l13project from both sides of straight ange portion 13 and are spaced fromeachother.

Outer frame portion 9 has a substantially U-shaped locking portion 20 ofwhich the flange-like legs 20 and l20" have inwardly directed ribs orteeth 21 spaced from each other. The ribs or teeth 21 areintermediate-1y spaced with respect to the ribs or teeth i13 of straight-ange portion 13 of the inner tra-me portion i8.

The fiangealike leg 20" of U-shaped :locking portion l20 is normallydisposed as shown in broken lines before outer frame portion 9 isrigidly connected to inner trame portion 8. A U-shaped piece ofinsulation 22 is placed around *flange portion 13, then the U-shapedlocking portion .20 with the flange-like leg 20" in its normal posit-ionis moved to embrace insulation 22 Iand ilange portion \13, :andthereafter the U-shaped locking portion 20 is clamped onto insulation=22 and straiglht flange portion 13 'with the ribs l13', 13 and 21intermeshing so that a rigid connection is effected between inner andouter frame portions without the use `of screws, rivets or such similardevices. |Ilhe connection betweenthe two frame portions is so rigid thatextremely large forces are necessary to separate the two portions oncethey are interconnected.

At the inner edge of leg 20', Ithere is integral therewith a section 23having a groove 24 therein. Groove 24 lhas a gasket or .sealing strip 25disposed therein.

Outer 4trarne portion 9 has a -ange-'like leg v26 which extends towardthe exterior section 27 of wa'll 5 and caulking compound is disposedtherebetween at 28 to rform a tight seal.

On the other side of web l10 `of channel member .11 of inner frameportion 8 there are spaced abutments 29. A stop member 30 of IU-shapedor channel cross section has flanges SI1 and 32 which engage againstabutments 29. Channel member 30 is iheld in place against web |10 ofchannel por-tion 11 by means of bolts, screws or some similar retainingmeans (not shown), or by a liish-hook like self-locking device againstabutments 29.

Flange 32 has .grooves 33 therein which receive the edges of a sealingstrip -or Igasket member 34. As can be seen, sealing strip 25 abuts-against sealing strip 34, and section 23 has a wide-r flange-like leg`3:5 abutting against sealing member 34.

`Inner portion 3a of sash 3 has a straight flange 36 on the outerperiphery thereof serving as means to engage and cooperate with stopmember 30 of the frame. Ribs 37 a-re disposed on each side of straight-flange 36 and are provided with teethdike projections 38. A sealingstrip 39 having a U-s-haped cross section embraces llange 36 and has itsfree edges positioned between tange B6 and members 37 with theprojections 38 of the, members 37 engaging and gripping and securelyclamping sealing strip 39.

Sealing strip 39 abuts against sealing strip 34, and against aprojecting ilange 30 of stop member 30.

The material forming the insulation or thermal-break between the innerand outer iframe portions l8 .and `9 is a material with a l-owconductance such as vinyl, neoprene, rubber, Hypallon `or other plasticand synthetic materials.

The .sealing strips or gaskets yare ormed of a flexible material such`as soft vinyl, neoprene, rubber, -or sponge material such `as spongeneoprene.

As can be discerned, the present invention comp-rises Ia rigid, strongand insulated connection between frame portions of .a Erame member inwhich a door Ior sash is to be mounted, effective insulation between thelframe member :and the sash 'or door member and Ia mounting o'f theframe member to the wall of a building.
